3 month old really bad cough don't know what to do

My 3 month old lb has had a cold since Boxing Day then developed a bad cough he had to have his 2 no lots of jabs on Wednesday and the nurse got us a appointment with the dr he basically couldn't of cared less basically said it will clear but today it sound like it is on his chest and sounds wheezy really don't know what to do ????

He has had his jabs so I really hope it's not whooping cough I was thinking of getting second opinion as the dr was really arrogant towards me made me feel like I was worrying over nothing I know I'm a first time mum but there was no need to be like that ,Just getting really worried over it all now

It's probably bronchiolitis that's doing the rounds. Keep an eye on temp, breathing and feeding, ring NHS direct or go to ooh of you are worried. My son has had it since he was 9 weeks and is now 16 weeks. Some days he sounds awful and coughs a lot and others he is fine. He was in hospital when his sats dropped low and they put him on oxygen. Hope baby is better soon, it's miserable when they are ill.
